It's just a dude that fell in love with an OS, let him enjoy it. Many people went through this phase, except he is very influential and high energy, so we hear a lot about his particular honeymoon. I for one am really enjoying his journey. Reminds me of myself when I first discovered Linux. I don't evangelize anymore, I helped to many people onto Linux only to have to watch them completely hate it, it's too painful ;)

Sure, a nice configuration.nix to try Ohmanix would be great, and much more convenient, easier to maintain and evolve than DHH's scripts. But that is not the point. Maybe he will try NixOS in a year, maybe he will land on some bootc distro. I don't care, I love his enthusiasm. Btw, on the Linux Unplugged podcast the hosts are following DHH closely and indeed experimenting with more modern ways of creating similar experiences. Partly fueled just by DHH's enthusiasm.
